A method for determining an amount of laundry in an at least approximately horizontally supported drum for laundry being driven by a universal drive motor at a washing and drying rpm is performed on the basis of observations of parameters of an operation in a laundry handling machine. A drive moment at the drum drive motor is determined during a drum startup phase, for operating the drum at a controlled handling rpm at which the laundry is not held against a wall of the drum by centrifugal force.
